The origins of AIDS Peter Chapell & Catherine Peix

AIDS : 26 million dead, 40 million infected.
It is now 20 years since the most devastating epidemic of history was unleashed on the planet. Its origin is still a mystery
The AIDS virus was born in Africa.
Chimpanzees are its natural carriers.
But how did it make the jump to mankind?
The scientific community remains divided over this question.
The preferred hypothesis is 'Natural Transfer': The virus jumped from one species to another through a bite or a wound and then spread among humans. According to the work of American geneticist Bette Korber, such an accident could have happened in 1931.
A minority group argues that it was caused by 'Human Mistake'. This theory suggests that an experimental polio vaccine, contaminated by the virus, might provide the key to the riddle. It postulates that one million Africans were administered the experimental vaccine between 1957 and 1960 in the Belgian colonies. This happens to be the very spot where, ten years later, the first AIDS cases in the world emerged.
The great, small world of Science is deeply divided on this issue -- by self-examination on one hand and complete denial on the other. Although hard to believe, it seems that, while fighting a deadly disease, medical research itself might have unleashed this pandemic plague.
In its search for the truth -- unearthing never-before-seen archive footage of researchers at work and bearing witness to memories of people who were there -- this film plunges the audience into an astonishing story of unprecedented scientific controversy.
